Why is Health.Global falling/rising?

As of 25-Aug, Healthcare Global Enterprises Ltd is experiencing a rise in its stock price, currently at Rs 678.90, reflecting an increase of 5.55 (0.82%). The stock has shown strong performance recently, with a 1-week return of 3.04% and a 1-month return of 19.11%, significantly outperforming the Sensex, which has only increased by 0.45% and 0.21% over the same periods, respectively. The stock is also close to its 52-week high, just 3.2% away from Rs 700.65, and has outperformed its sector by 1.46%. However, it is important to note that while the stock has generated a return of 77.10% over the past year, its profits have decreased by 24.9%, indicating some underlying weaknesses.
In the broader market context, the stock's recent performance is notable as it has consistently outperformed the BSE500 over the last three years, one year, and three months. Despite this positive trend, there are concerns regarding the company's long-term fundamental strength, highlighted by a high Debt to EBITDA ratio of 3.91 times and a Return on Capital Employed (ROCE) of 5.92%. Additionally, the significant proportion of pledged promoter shares, which has increased by 83.01% over the last quarter, could exert downward pressure on the stock in a falling market. Overall, while the stock is currently rising, these negative factors may pose risks for future performance.
